Forex Source Information - is this a custom integration

[Ascar699]

Crater team, please clarify a few points to someone who is new to your platform.

After some struggling with settings I was able to install Crater in Docker. When I started exploring the system I came to understanding that I can't connect to any Forex datasource - messages were like 'You have to be on a certain plan to connect this datasource' or simple 'Not Allowed' (Open Exchange Rate). This made me again go through the comparison of editions here https://craterapp.com/enterprise. My question is whether integration with a forex data service provider falls under 'Custom Integrations'?

I also would like to understand what exactly else is not available in self-hosted edition? What is the difference between Basic White Labeling and Premium one?

Thanks in advance
